Canada is known as a centre of excellence in mining geophysics, and much of the credit for this achievement goes to Harold Seigel, an extraordinary geophysicist who conceived and pioneered several new methods of mineral exploration.

When the modern age for exploration geophysics began more than four decades ago, Norman Paterson was one of its leaders. Today, he is known worldwide for his innovations in geophysical technology and skilled practice of geophysical techniques and interpretation.
